What is a tube made of?
A tube is made of Butyl rubber or natural rubber.
Butyl is a very elastic and airtight synthetic rubber, but other fillers are necessary to make up the rubber compound. The quality of a tube can vary significantly depending on the rubber compound.
Every tube also needs a valve, which is bonded to the tube during the vulcanization process.
Which special features does a Zihai tube offer?
Besides the quality of the ingredients, the purity of the rubber compound is decisive for the quality of the tube. Before extrusion, the basic material is forced through a total of seven filters under enormous pressure.
All tubes are inserted and inflated into a mold for the vulcanizing process. Only this ensures an even wall thickness and high air retention.
All tubes are inflated and stored for 24 hours to test for air retention.
Afterwards, every tube is carefully checked individually by visual inspection. The special quality control prevents unpleasant surprises.
The Zihai tube has been valued by many dealers for its high reliability for many years.
A tube is not just a tube.
Airtightness. Apart from the quality of the ingredients, the purity of the rubber mixture is crucial to the quality of the tube. The base material is therefore sieved at enormous pressure through seven filters before being extruded. All tubes are inserted into a mould and inflated for vulcanization to ensure constant wall thickness and high air pressure retention.
Reliability. All tubes are inflated and stored for 24 hours in order to test for air pressure retention. Afterwards each, individual tube undergoes a careful visual inspection. This special quality control helps prevent unpleasant surprises.
Valve. All valves are copper and threaded and some valve inserts are replaceable. Also tubes with the classic valve are capable of pressure testing thanks to a high pressure valve seal. And it is plain to see as each tube is crowned with dust cap.
